samba - Jan 2013 - AIX: TypeError: unsupported operand type(s) for +: '_hashlib.HASH' and 'str'

Hi there!
   We're trying to compile Samba 4.0.0 on a fresh install of AIX 6.1
(6100-02-01-0847), with Python RPM's from perzl.org installed into
/opt/freeware.  We're also using XLC 12.1.

Unfortunately, we can't even run ./configure, as we're getting errors
from the waf system.  Here's what we get:

bash-4.2# pwd
/admin/tst/build/samba-4.0.0
bash-4.2# ./configure --help
Traceback (most recent call last):
  File "./buildtools/bin/waf", line 75, in <module>
    import Scripting
  File
"/admin/tst/build/samba-4.0.0/buildtools/wafadmin/Scripting.py", line
9, in <module>
    import Utils, Configure, Build, Logs, Options, Environment, Task
  File "/admin/tst/build/samba-4.0.0/buildtools/wafadmin/Utils.py",
line 134, in <module>
    from hashlib import md5
  File "/opt/freeware/lib/python2.6/hashlib.py", line 117, in
<module>
    exec funcName + ' = f'
TypeError: unsupported operand type(s) for +: '_hashlib.HASH' and
'str'
bash-4.2#

Python was installed just for this purpose, but otherwise we don't deal with
it much.  I'd like to be able to build as many of the Samba 4.0 features as
possible, so I don't want to revert to the old toolchain, but I'm under
a deadline of ~1 week, so I'll try that next if I can't get the waf
system to work.
Anyone have any insight as to what we might be hanging up on?

Many many thanks in advance!!

I think the next step is to change your python install to something as
close to the upstream python as possible.  We supply an
'install_with_python.sh' script which installs a (now old) but known
working version, but you should also have reasonable luck with just the
current python 2.7

I've been killing myself trying to get the "reccomended" Python
2.6.5 from the install_with_python.sh script to work.  Even rebuilt the AIX
build system with minimal packages only and nothing from perzl.  Still no-go.

Anyone manage to get Python 2.6.5 to build on AIX with XLC, and if so, what
configure options did you use?

If it pukes this one last time, I think I'll give up and try 2.7.3 like you
suggest.  What options did you use to build that?  Were you using XLC or GCC?

Thanks!

2.6.5 failed.  I'm building Samba into /opt/samba-4.0.0.  I built a private
copy of 2.7.3 into /opt/samba-4.0.0/python using only the options specified in
install_with_python.sh.  Worked no prob.

Thanks!
